Posteriors for \(\Omega _K\)  are shown in the right hand panel of
Fig. REF  for various likelihood combinations. As with
\(A_L\) , the Planck results are consistent with a moderate statistical
fluctuation in the temperature spectra that favours closed universes
at about the \(2 \sigma \)  level. With the addition of BAO and/or
Planck lensing data, we find strong evidence to support a spatially
flat Universe. Given the recent interest in models with spatial
curvature, we have given a more detailed statistical analysis of the
results from the 12.5HMcln likelihood in [1]},
including the role of assuming a uniform prior in \(\Omega _K\) .
